Description

Technical Field

[0001] The invention relates to the technical field of packed tower parts, and in particular to a non-metallic packing support grid. Background Art

[0002] Packed towers are a mass transfer equipment that uses the packing in the tower as a contact structure between the gas and liquid phases. They are widely used in oil refining, chemical industry, fertilizer and other fields. The tower body of the packed tower is a columnar structure, mostly cylindrical, and its internal parts include liquid distributors, packing, packing support grids, etc. The packing support grid is installed in the tower, and the packing is neatly stacked on the packing support grid. The liquid is sprayed from the top of the tower to the packing through the liquid distributor and flows down from the surface of the packing, while the gas is fed from the bottom of the tower and continuously passes through the gaps of the packing in a countercurrent state with the liquid. The gas and liquid are in close contact on the surface of the packing for mass transfer.

[0003] Among them, the main function of the packing support grid is to bear the weight of the packing and the liquid in the packing and ensure smooth gas-liquid circulation. Since the packing support grid is often in a high temperature, high humidity and corrosive environment, there are strict requirements for the mechanical strength of the packing support grid. At present, for most working conditions, metal materials such as stainless steel, titanium, zirconium, and Hastelloy alloy are usually used in chemical separation to manufacture and process the packing support grid. However, for the separation operation conditions of strong acids (such as hydrofluoric acid, organic acids, and halogens) at relatively high temperatures, metal materials including high alloys have significant corrosion and life problems in actual operation, so non-metallic materials with excellent mechanical and chemical properties are required. In response to this packing support grid requirement, carbon fiber materials with good mechanical properties and corrosion resistance are used in the prior art to manufacture the packing support grid.

[0004] From the above, in the prior art, the manufacturing and processing technology of the filler support grid made of carbon fiber material also has certain problems. Although silicon carbide material has excellent high temperature resistance and corrosion resistance, it has high hardness and high machining difficulty. Compared with metal, it does not support processing methods such as welding. Therefore, as disclosed in the invention with the existing authorization announcement number US7988931B2, the filler support grid generally includes transverse partitions and longitudinal partitions, and the transverse partitions and the longitudinal partitions are cross-arranged, wherein the transverse partitions and / or the longitudinal partitions are provided with U-shaped notches, and the transverse partitions and the longitudinal partitions are plugged into each other at the U-shaped notches to form a mesh grid structure. However, since the transverse partitions and the longitudinal partitions are made of carbon fiber material, the U-shaped notches will cut off the continuous fibers, thereby resulting in a decrease in the mechanical properties of the filler support grid. In other words, the currently used mesh grid structure of carbon fiber material is applied to the support grid of silicon carbide material, which will also seriously damage the continuity and mechanical properties inside the silicon carbide support grid.

[0005] Therefore, the above problems need to be solved urgently. Summary of the invention

[0006] The purpose of the present invention is to provide a non-metallic filler support grid to solve the problem that the traditional non-metallic filler support grid is composed of a transverse partition and a longitudinal partition connected to each other at a U-shaped notch, and the U-shaped notch will cut off the continuous fiber, thereby reducing the mechanical properties of the non-metallic filler support grid.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0015] Preferably, the non-metallic filler support grid further comprises a support beam, which is placed on a support plate disposed in the filler tower and supported below all the partitions.

[0016] Preferably, the supporting beam extends radially along the positioning ring.

[0017] Preferably, the supporting crossbeam is hollow, and through holes are provided on both sides of the supporting crossbeam along the extending direction of the dividing line of the positioning ring.

[0018] Preferably, the positioning ring is made of carbon fiber composite material, and the partition is made of silicon carbide material.

[0019] Preferably, the distances between any two adjacent partitions are equal.

[0020] Beneficial effects of the present invention:

Since there is no notch on the partition, the mechanical properties of the partition are relatively high, so that the mechanical properties of the non-metallic filler support grid as a whole are relatively high.

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] Based on the content mentioned above, since the manufacturing and processing methods of the filler support grid made of silicon carbide are different from those of the traditional stainless steel filler support grid, and the manufacturing and processing technology of the existing carbon fiber filler support grid also has certain problems, this invention is made.

[0038] See also Figures 1 to 8 The present embodiment provides a non-metallic filler support grid, which includes a positioning ring 210 and a partition 220. The positioning ring 210 is divided into a plurality of petals 211 along its radial direction. The positioning ring 210 can be placed on a support ring 110 arranged in a packing tower 100. It can be understood that the support ring 110 is arranged on the inner wall of the packing tower 100, and a partition 220 is placed between any two adjacent petals 211. The two ends of the partition 220 are clamped by the two adjacent petals 211, and the two ends of the partition 220 are placed on the support ring 110.

[0039] That is, in this embodiment, during the production of the positioning ring 210, the positioning ring 210, which is originally an integrated structure, can be cut into a plurality of petals 211, and a separation groove is formed between two adjacent petals 211. During the installation of the positioning ring 210 into the packing tower 100, a partition 220 is placed between two adjacent petals 211, that is, the end of the partition 220 is placed in the separation groove, and the partition 220 is in contact with the groove wall of the separation groove. It can be understood that for the positioning ring 210 placed on the support ring 110, the outer periphery of the positioning ring 210 is in contact with the inner wall of the packing tower 100.

[0040] As described above, in this embodiment, the positioning ring 210 is used to fix the partition 220, and the filler is stacked on a plurality of partitions 220, that is, the partition 220 is a support member for carrying the filler, and the partition 220 is directly overlapped on the support ring 110 in the packing tower 100, and the positioning ring 210 is only used as a fixing member for fixing the partition 220, and does not bear the pressure of the filler. Since there is no notch on the partition 220, the mechanical properties of the partition 220 are relatively high, so that the mechanical properties of the non-metallic filler support grid as a whole are relatively high.

[0041] It can be understood that, in this embodiment, the height of the positioning ring 210 is equal to the height of the partition 220 , thereby ensuring that the positioning ring 210 can firmly fix the partition 220 .

[0042] It is worth noting that, since the positioning ring 210 does not have any mechanical requirements and only plays a role in installation and positioning, the material requirements can be relaxed. Specifically, in this embodiment, the positioning ring 210 is made of a carbon fiber composite material. For example, the positioning ring 210 is made of a carbon fiber reinforced carbon material (CFRC), so that it can maintain stable performance in a high temperature, high humidity and corrosive environment. Of course, in other optional embodiments, the positioning ring 210 can also be made of a hard PTFE (polytetrafluoroethylene) material or completely made of a silicon carbide material. This embodiment does not impose specific restrictions on this. Specifically, for working conditions in an oxidizing environment, the positioning ring 210 can be completely made of a silicon carbide material, and for low temperature working conditions, the positioning ring 210 can be made of a hard PTFE material.

[0043] In addition, the partition 220 is made entirely of silicon carbide material, so that on the one hand it can maintain stable performance in a high temperature, high humidity and corrosive environment, and on the other hand it also has high mechanical properties, so that it can support the filler more stably.

[0044] It is worth noting that, in the present embodiment, the partition 220 is a solid plate. Of course, in other optional embodiments, the partition 220 may also be a hollow plate, and ventilation holes are provided at the top and bottom of the partition 220 to facilitate the upward flow of gas.

[0045] In addition, one of the two adjacent petals 211 is provided with a first hole 2111, and the other of the two adjacent petals 211 is provided with a second hole 2112. The first hole 2111 is opposite to the second hole 2112. The end of the partition 220 is provided with a third hole 221. The non-metallic filler support grid also includes a fixing pin 230. The fixing pin 230 passes through the third hole 221 and the two ends are respectively inserted into the first hole 2111 and the second hole 2112, thereby ensuring that the positioning ring 210 can more firmly fix the partition 220, thereby ensuring the flatness and stability of the non-metallic filler support grid.

[0046] As described above, the specific installation process of the non-metallic filler support grid is as follows: a plurality of petals 211 are placed one by one on the support ring 110, and a plurality of petals 211 are placed one by one on the support ring 110 from left to right, and the first plug hole 2111 is set on the right section of the petal 211, and the second plug hole 2112 is set on the left section of the petal 211. After each petal 211 is placed, a partition 220 is placed on one side of the petal 211, and a fixing pin 230 is passed through the third plug hole 221 of the partition 220 and inserted into the first plug hole 211 of the petal 211. The positioning ring 210 is inserted into the hole 2111, and then, another petal 211 is placed on the right side of the newly placed partition 220, and the second hole 2112 on the newly placed petal 211 is aligned with the fixing pin 230, so that the fixing pin 230 is inserted into the second hole 2112 of the newly placed petal 211, and so on, so that the entire positioning ring 210 can be installed in the packing tower 100, and a partition 220 is placed between any two adjacent petals 211, and the two adjacent petals 211 and the partition 220 clamped therebetween are fixed by the fixing pin 230.

[0047] It is worth noting that the fixing pin 230 may be made of graphite material, carbon fiber reinforced carbon material, PTFE material, or silicon carbide material, and this embodiment does not impose any specific limitation on this.

[0048] Furthermore, a third plug hole 221 is provided at both ends of the partition 220, a first plug hole 2111 is provided on both sides of the dividing line between one of the two adjacent petals 211, and a second plug hole 2112 is provided on both sides of the dividing line between the other of the two adjacent petals 211, thereby ensuring that the two adjacent petals 211 and the partition 220 clamped therebetween can be fixed by the fixing pin 230 on both sides along the extension direction of the dividing line, thereby further ensuring that the positioning ring 210 can more firmly fix the partition 220.

[0049] In addition, in the present embodiment, two third holes 221 are provided at both ends of the partition 220, two first holes 2111 are provided on both sides of the dividing line for one of the two adjacent petals 211, and two second holes 2112 are provided on both sides of the dividing line for the other of the two adjacent petals 211. That is, for the two adjacent petals 211 and the partition 220 clamped therebetween, any side along the extension direction of the dividing line can be fixed by two fixing pins 230, thereby further ensuring that the positioning ring 210 can more firmly fix the partition 220.

[0050] It is understandable that in other optional embodiments, three or more third holes 221 may be provided at both ends of the partition 220, and accordingly, one of the two adjacent petals 211 may be provided with three or more first holes 2111 on both sides along the dividing line, and the other of the two adjacent petals 211 may be provided with three or more second holes 2112 on both sides along the dividing line. This embodiment does not impose any specific restrictions on this.

[0051] Furthermore, the non-metallic filler support grid also includes an annular gasket 240, which is placed on the support ring 110, and the positioning ring 210 and the partition 220 are both placed on the annular gasket 240, that is, before installing the positioning ring 210 and the partition 220, the annular gasket 240 is first placed on the support ring 110, and then the positioning ring 210 and the partition 220 are assembled. Since the annular gasket 240 is arranged between the partition 220 and the support ring 110, the partition 220 can evenly transfer the pressure it receives to the support ring 110, thereby avoiding the occurrence of excessive pressure at a single point, thereby improving the stability of the partition 220.

[0052] It is worth noting that, in the present embodiment, the annular gasket 240 is made of a high temperature resistant and corrosion resistant plastic material such as polytetrafluoroethylene, and the present embodiment does not impose any specific limitation on this.

[0053] It is also worth mentioning that the annular gasket 240 is formed by splicing a plurality of sheets 241. Compared with the one-piece molding structure, the present embodiment can place a plurality of sheets 241 into the packing tower 100 one by one, and then splice a plurality of sheets 241 in the packing tower 100 to form an annular gasket 240, that is, the present embodiment can facilitate the placement and assembly of the gasket into the packing tower 100 in an annular shape.

[0054] Furthermore, the non-metallic filler support grid also includes a support beam 250, which is placed on a support plate 120 disposed in the packing tower 100 and supported underneath all partitions 220, thereby further improving the mechanical properties of the non-metallic filler support grid and ensuring that the partitions 220 can more stably support the filler.

[0055] As described above, in this embodiment, the supporting beam 250 extends in the radial direction of the positioning ring 210 , so as to fully support all the partitions 220 .

[0056] In addition, the support beam 250 is hollow, and through holes 251 are provided on both sides of the support beam 250 along the extension direction of the dividing line of the positioning ring 210, thereby connecting the spaces on both sides of the support beam 250 along the extension direction of the dividing line of the positioning ring 210, so as to ensure that the air pressure on both sides of the support beam 250 along the extension direction of the dividing line of the positioning ring 210 is the same, thereby ensuring the stability of the support beam 250.

[0057] Based on the above, it should be noted that, in the present embodiment, the distance between any two adjacent partitions 220 is equal, that is, in the present embodiment, a plurality of partitions 220 are evenly arranged in the packing tower 100, thereby ensuring that the gas can flow upward evenly on the one hand, and can also support the packing more stably on the other hand.

[0058] It is understandable that this embodiment does not impose any specific restriction on the number of petals 211 included in the positioning ring 210, that is, this embodiment does not impose any specific restriction on the number of partitions 220, and the number of petals 211 and the number of partitions 220 are specifically selected according to actual conditions.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
